Solution Overview
Problem
Existing fluid cooling devices, particularly in cooling towers, face challenges in achieving uniform liquid distribution, leading to inefficiencies in cooling performance and increased maintenance due to nozzle blockages and high pressure losses.
Innovation Solution
A fluid cooling device with a liquid distribution system featuring tangentially attached full cone nozzles, which provide a rotationally symmetrical nozzle chamber and a connecting piece aligned at right angles and offset from the vertical axis, ensuring a twisting movement of the water jet without swirl devices, thus preventing clogging and reducing pressure losses.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If plate nozzles with baffle plates are used to distribute liquid, then liquid distribution uniformity is improved, but the distance from extension tube to plate must be large (0.8m to 1.2m) which increases device height
Solution Approach 1:
The nozzle is divided into separate functional components: the extension tube and the baffle plate are detached, allowing the baffle plate to be positioned optimally without requiring a large fixed distance from the extension tube. This segmentation enables better liquid distribution uniformity while reducing the overall device height.
2Manufacturing precision
If swirl devices are used in nozzles to improve liquid distribution, then liquid distribution uniformity is improved, but pressure losses increase and nozzles are prone to blockages
Solution Approach 1:
The harmful swirl devices that cause pressure losses and blockages are completely removed from the nozzle design. Instead, a simple baffle plate is used to achieve liquid distribution uniformity without the negative effects of traditional swirl devices, thereby reducing pressure losses and preventing nozzle blockages.
3Productivity
If internal cooling components are used in cooling towers, then cooling performance is improved, but constant soiling and clogging of these components occurs with contaminated liquids
Solution Approach 1:
The cooling tower system uses the contaminated liquid itself to clean the baffle plate through the liquid flow and spray action, preventing accumulation of deposits. The liquid distribution mechanism inherently resists soiling and clogging without requiring additional cleaning systems or protective measures.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution achieves uniform liquid distribution with low energy losses, reducing maintenance needs and enhancing cooling efficiency by maintaining a compact design and preventing nozzle blockages, resulting in improved performance and cost-effectiveness.
Implementation Method 1
the connecting piece being in relation to the vertical axis of rotation of the nozzle chamber is aligned at right angles and offset thereto and wherein the outlet opening is offset in the direction of the connecting piece with respect to the vertical axis of rotation of the nozzle chamber
Implementation Method 2
Cooling towers are used to cool a fluid, such as a liquid. The fluid to be cooled is often water. However, acid cooling towers are also common, i.e. an acid is cooled in the cooling tower using ambient air, also according to the principle of evaporative cooling.
